Volt OverviewVolt OverviewExtended-Range Electric VehicleAvailable for mass purchase in
2010 as a 2011 model yearDesigned to meet the needs of
75% of America's daily commuters
Advanced lithium-ion battery pack means no gasoline and zero emissions for up to 40 miles

might be more expensive ($40,000)0 to 60 in 8.5 secondsa top speed of at least 100 mphRegenerative braking
E-REV (Extended-Range E-REV (Extended-Range Electric Vehicle)Electric Vehicle)a plug-in range-extended electric
vehicle with an on-board gasoline generator.
large battery charged from home electric outlet and connected to an electric motor.
electric motor directly propels the carbattery lasts for the first 40 miles,
then the on-board gasoline/E85 generator will power up
Recharges battery which continues to directly propel car
Isn’t this a hybrid?Isn’t this a hybrid?Most hybrids today are parallel hybrids
◦ small electric motor for low speed driving◦ regular gas engine for acceleration and faster
speed driving◦ both engines work side by side or in parallel
The Volt is a series vehicle◦ the electric motor powers the car at all times◦ the gas engine is just a generator, making
electric to keep the batteries in a steady state of charge.

Fuel EfficiencyFuel EfficiencyA bit complicated, the EPA doesn’t
know what to doWhen the battery has been
discharged to its lower limit set-point, the gas engine kicks in to recharge the battery (at approx. 40 miles)
The gas engine is rated at 55 mpgWhen the battery is recharged to an
upper limit set-point the gas engine turns off again
To calculate the fuel efficiency for drives longer than 40 miles use the following formula: Total MPG = 55*M/(M-40)
Volt has a potential range of 640 miles on a single tank of fuel
Range can be increased by refueling without the need to recharge
0.65 cents per kW = $0.85 to recharge
EmissionsEmissions Zero emissions for trips under 40 miles Above 40 miles emissions will be similar to other 4-
cyl low displacement gasoline powered automobile. General Motors apparently claims that operating
the Volt for a year, results in the reduction of about 4.4 tonnes (4.3 LT/4.9 ST) in CO2 emissions as compared to a typical U.S. car
Battery charging emissions American Council for an Energy Efficient Economy
(ACEEE) ◦ a typical plug-in hybrid electric vehicle is expected to
achieve about a 15% reduction in net CO2 emissions compared to the driver of a regular hybrid,
◦ in areas where less than 80% of grid-power comes from coal-burning power plants, local net CO2 emissions will decrease
Potential for charge with green energy sources
Concerns about the VoltConcerns about the VoltBattery
◦“Industry sources tell us the claims about the Volt’s batteries are wildly optimistic when weight, cost, capacity, and longevity are considered.”
◦Battery supplier still not decided◦Technology is still too-expensive, $10,000 vs.
$5,000◦With anticipated release date of 2010, this
technology should be solidified◦Safety? Toyota was saying that safety was a
big issue with the volt, but are now embracing similar technology.
Cost◦$30,000 not realistic◦Even at $50,000 GM wouldn’t see much
profit◦Government incentives a big wildcard◦Gas at or near $3.60 per gallon= $1500 of
savings annually.◦ Volt costs extra $20,000 compared with
conventional compacts.◦Recouping the investment likely to take 10
years, which point the battery must be replaced
The Future of GMThe Future of GMViability Plan presented to
congress TODAYNew administration in favor of
green energy and green jobs???
